Explaining his now famous parody in Social Text's "Science Wars" issue, Alan Sokal writes in Dissent ("Afterword", Fall 1996): But why did I do it? I confess that I'm an unabashed Old Leftist who never quite understood how deconstruction was supposed to help the working class. And I'm a stodgy old scientist who believes, naively, that there exists an external world, that there exist objective truths about that world, and that my job is to discover some of them. There is much to note in this "confession." Why choose a hoax on Social Text to make these points? Did Sokal believe its editors were unabashed deconstructionists who doubted the existence of an external world or that they were anti-science? If so, he has either misread the burden of its seventeen-year history or was capricious in his choice. If not, then he has perpetuated the saddest hoax of all: on himself. For the fact is that Social Text, of which I am a founder and in whose editorial collective I served until this year, has never been in the deconstructionist camp; nor do its editors or the preponderance of its contributors doubt the existence of a material world. What is at issue is whether our knowledge of it can possibly be free of social and cultural presuppositions.
